IEEE 1149.1 is an industry standard test protocol that sometimes is incorrectly referred to as JTAG after the original European Joint Test Action Group (JTAG). Today's 1149.1 technology uses boundary-scan cells on device IO pins to provide virtual access to key nets and pins within a printed c...
开发工程师通过结合使用RealView MDK的调试器和ULINK2,可以方便的在目标硬件上进行片上调试(使用on-chip JTAG,SWD和OCDS)、Flash编程。 七、调试器Pin脚 市面上有很多兼容 SWD 和 JTAG 协议的MCU和调试适配器,他们通常通过具有一组下载调试引脚,来实现下载和调试功能,这些引脚内部复用到SWD外设和JTAG外设。 SWD的引...

最近做了一个项目,项目方案是以DSP+FPGA为平台解决,经历了前期大量啃资料,原理设计,PCB设计,投板贴片后,目前正在调试阶段,过程中遇到了标题所述DSP TMS320C6655 JTAG连不上的问题。以下是我查找原因的辛酸史: 先介绍下DSP的启动方案:DSP的所有供电电源的使能引脚以及DSP的复位引脚和GPIO配置都由FPGA控制 ...
JTAG Functional Test system (JFT) is a simple to use DLL Application Program Interface (API) with a series of software modules that support boundary-scan test and programming activities
这个intest指令,就是用来测试jtag接口的连接情况,看看它通不通,好不好使。 再来说说陕西方言。jtag的intest指令,就像咱们陕西的羊肉泡馍一样,得一步一步来,不能急。你得先把馍掰碎,再浇上羊肉汤,这样才能吃出味道来。同样,使用intest指令的时候,也得按照步骤来,先测试这个,再测试那个,才能确保jtag接口没问题...
